Changelog

Main

  • Contrib: Refactored dice.roll contrib function to use safe_eval. Can now optionally be used as dice.roll("2d10 + 4 > 10"). Old way works too.

Evennia 2.0.1

June 17, 2023

  • Fix: A look-bug in the ExtendedRoom contrib (InspectorCaracal)

Evennia 2.0.0

June 10, 2023

  • Possible backwards incompatibility: Updated contrib ExtendedRoom now supports arbitrary room-states, state-based descriptions, embedded funcparser tags, details and random messages. While this feature is made to be as backwards-compatible as possible, so many people depend on this contrib class that we are updating the major Evennia version to indicate the big changes.
  • New Contrib: Container typeclass with new commands for storing and retrieving things inside them (InspectorCaracal)
  • Feature: Add TagCategoryProperty for setting categories with multiple tags as properties directly on objects. Complements TagProperty.
  • Feature: Attribute-support for saving/loading deques with maxlen= set.
  • Feature: Refactor to provide evennia.SESSION_HANDLER for easier overloading and less risks of circular import problems (Volund)
  • Fix: Allow webclient's goldenlayout UI (default) to understand msg cls kwarg for customizing the CSS class for every resulting div (friarzen)
  • Fix: The AttributeHandler.all() now actually accepts category= as keyword arg, like our docs already claimed it should (Volund)
  • Fix: TickerHandler store key updating was refactored, fixing an issue with updating intervals (InspectorCaracal)
  • Docs: Removed warning about Python3.11 on Windows; upstream Twistd now supports 3.11 on Windows.
  • Docs: New Beginner-Tutorial lessons for NPCs, Base-Combat Twitch-Combat and Turnbased-combat (note that the Beginner tutorial is still WIP).
  • Stabilize how to make the major update in the docs.
  • Fix: A lot of other minor bug fixes.

Evennia 1.3.0

Apr 29, 2023

  • Feature: Better ANSI color fallbacks (InspectorCaracal).

  • Fix: Have EvenniaTestCase properly flush idmapper cache (bradleymarques)
  • Tools: More unit tests for scripts (Storsorken)
  • Docs: Made separate doc pages for Exits, Characters and Rooms. Expanded on how to change the description of an in-game object with templating.
  • Docs: A multitude of doc issues and typos fixed.

Evennia 1.2.1

Feb 26, 2023

  • Bug fix: Make sure command parser gives precedence to longer cmd-aliases. So if sending smile at and the cmd smile has alias smile at, the match is ordered so the result is never interpreted as smile with an argument at.
  • Bug fix: || (escaped color tags) were parsed too early in help entries, leading to colors when wanting a | separator
  • Bug fix: Make sure spawned objects get typeclass_path pointing to the true location rather than alias (in line with create_object).
  • Bug fix: Building Menu contrib menu no using Replace over Union mergetype to avoid clashing with in-game commands while building
  • Feature: RPSystem contrib sdesc command can now view/delete your sdesc.
  • Bug fix: Change so script obj = [scriptname|id] is required to manipulate scripts on objects; script scriptname|id only works on global scripts.
  • Doc: Add warning about Django-wiki (in wiki tutorial) only supporting Django <4.0.
  • Doc: Expanded XYZGrid docstring to clarify MapLink class will not itself spawn anything, children must define their prototypes explicitly.
  • Doc: Explained why AttributeProperty.at_get/set will not be called if accessing the Attribute from the AttributeHandler (bypassing the property)
  • Bug fix: Evtable options showed spurious empty lines if set without desc
  • Usage fix: The teleport: and teleport_here: locks where checked in CmdTeleport, but not actually set on any entities. These locks are now set with defaults on all objects,characters,rooms and exits.

  • Bug fix: $an() inlinefunc didn't understand to use 'an' words starting with a capital vowel
  • Bug fix: Another case of the 'duplicate Discord bot connections' bug (InspectorCaracal)
  • Fix: Make XYZGrid contrib's MapParserErrors more succinct

Evennia 1.1.1

Jan 15, 2023

  • Bug fix: Better handler malformed alias-regex given to nickhandler. A regex-relevant character in a channel alias could cause server to not restart.

  • Bug fix release. Main issue was reconnect bug for discord bot.

Evennia 1.0.0

2019-2022

Changed to using main branch to follow github standard. Old master branch remains for now but will not be used anymore, so as to not break installs during transition.

Also changing to using semantic versioning with this version.

Increase requirements: Django 4.1+, Twisted 22.10+ Python 3.10, 3.11. PostgreSQL 11+.

  • New drop:holds() lock default to limit dropping nonsensical things. Access check defaults to True for backwards-compatibility in 0.9, will be False in 1.0
  • REST API allows you external access to db objects through HTTP requests (Tehom)
  • Object.normalize_name and .validate_name added to (by default) enforce latinify on character name and avoid potential exploits using clever Unicode chars (trhr)
  • New utils.format_grid for easily displaying long lists of items in a block.
  • Using lunr search indexing for better help matching and suggestions. Also improve the main help command's default listing output.
  • Added content_types indexing to DefaultObject's ContentsHandler. (volund)
  • Made most of the networking classes such as Protocols and the SessionHandlers replaceable via settings.py for modding enthusiasts. (volund)
  • The initial_setup.py file can now be substituted in settings.py to customize initial game database state. (volund)
  • Added new Traits contrib, converted and expanded from Ainneve project.
  • Added new requirements_extra.txt file for easily getting all optional dependencies.
  • Change default multi-match syntax from 1-obj, 2-obj to obj-1, obj-2.
  • Make object.search support 'stacks=0' keyword - if >0, the method will return N identical matches instead of triggering a multi-match error.
  • Add tags.has() method for checking if an object has a tag or tags (PR by ChrisLR)
  • Make IP throttle use Django-based cache system for optional persistence (PR by strikaco)
  • Renamed Tutorial classes "Weapon" and "WeaponRack" to "TutorialWeapon" and "TutorialWeaponRack" to prevent collisions with classes in mygame
  • New crafting contrib, adding a full crafting subsystem (Griatch 2020)
  • The rplanguage contrib now auto-capitalizes sentences and retains ellipsis (...). This change means that proper nouns at the start of sentences will not be treated as nouns.
  • Make MuxCommand lhs/rhslist always be lists, also if empty (used to be the empty string)
  • Fix typo in UnixCommand contrib, where help was given as --hel.
  • Latin (la) i18n translation (jamalainm)
  • Made the evennia dir possible to use without gamedir for purpose of doc generation.
  • Make Scripts' timer component independent from script object deletion; can now start/stop timer without deleting Script. The .persistent flag now only controls if timer survives reload - Script has to be removed with .delete() like other typeclassed entities.
  • Add utils.repeat and utils.unrepeat as shortcuts to TickerHandler add/remove, similar to how utils.delay is a shortcut for TaskHandler add.
  • Refactor the classic red_button example to use utils.delay/repeat and modern recommended code style and paradigms instead of relying on Scripts for everything.
  • Expand CommandTest with ability to check multiple message-receivers; inspired by PR by user davewiththenicehat. Also add new doc string.
  • Add central FuncParser as a much more powerful replacement for the old parse_inlinefunc function.
  • Attribute/NAttribute got a homogenous representation, using intefaces, both AttributeHandler and NAttributeHandler has same api now.
  • Add evennia/utils/verb_conjugation for automatic verb conjugation (English only). This is useful for implementing actor-stance emoting for sending a string to different targets.
  • New version of Italian translation (rpolve)
  • utils.evmenu.ask_yes_no is a helper function that makes it easy to ask a yes/no question to the user and respond to their input. This complements the existing get_input helper.
  • Allow sending messages with page/tell without a = if target name contains no spaces.
  • New FileHelpStorage system allows adding help entries via external files.
  • sethelp command now warns if shadowing other help-types when creating a new entry.
  • Help command now uses view lock to determine if cmd/entry shows in index and read lock to determine if it can be read. It used to be view in the role of the latter. Migration swaps these around.
  • In modules given by settings.PROTOTYPE_MODULES, spawner will now first look for a global list PROTOTYPE_LIST of dicts before loading all dicts in the module as prototypes.
  • New Channel-System using the channel command and nicks. Removed the ChannelHandler and the concept of a dynamically created ChannelCmdSet.
  • Add Msg.db_receiver_external field to allowe external, string-id message-receivers.
  • Renamed app.css to website.css for consistency. Removed old prosimii-css files.
  • Remove mygame/web/static_overrides and -template_overrides, reorganize website/admin/client/api into a more consistent structure for overriding. Expanded webpage documentation considerably.

  • Update and fix dummyrunner with cleaner code and setup.
  • Made iter_to_str format prettier strings, using Oxford comma.
  • Added an MXP anchor tag to also support clickable web links.
  • New tasks command for managing tasks started with utils.delay (PR by davewiththenicehat)
  • Make help index output clickable for webclient/clients with MXP (PR by davewiththenicehat)
  • Custom evennia launcher commands (e.g. evennia mycmd foo bar). Add new commands as callables accepting *args, as settings.EXTRA_LAUNCHER_COMMANDS = {'mycmd': 'path.to.callable', ...}.
  • New XYZGrid contrib, adding x,y,z grid coordinates with in-game map and pathfinding. Controlled outside of the game via custom evennia launcher command.
  • Script.delete has new kwarg stop_task=True, that can be used to avoid infinite recursion when wanting to set up Script to delete-on-stop.
  • Command executions now done on copies to make sure yield don't cause crossovers. Add Command.retain_instance flag for reusing the same command instance.
  • The typeclass command will now correctly search the correct database-table for the target obj (avoids mistakenly assigning an AccountDB-typeclass to a Character etc).
  • Merged script and scripts commands into one, for both managing global- and on-object Scripts. Moved CmdScripts and CmdObjects to commands/default/building.py.
  • Keep GMCP function case if outputfunc starts with capital letter (so cmd_name -> Cmd.Name but Cmd_nAmE -> Cmd.nAmE). This helps e.g Mudlet's legacy Client_GUI implementation)
  • Prototypes now allow setting prototype_parent directly to a prototype-dict. This makes it easier when dynamically building in-module prototypes.
  • RPSystem contrib was expanded to support case, so /tall becomes 'tall man' while /Tall becomes 'Tall man'. One can turn this off if wanting the old style.
  • Change EvTable fixed-height rebalance algorithm to fill with empty lines at end of column instead of inserting rows based on cell-size (could be mistaken for a bug).
  • Split return_appearance hook with helper methods and have it use a template string in order to make it easier to override.
  • Add validation question to default account creation.
  • Add LOCALECHO client option to add server-side echo for clients that does not support this (useful for getting a complete log).
  • Make @lazy_property decorator create read/delete-protected properties. This is because it's used for handlers, and e.g. self.locks=[] is a common beginner mistake.
  • Add $pron() inlinefunc for pronoun parsing in actor-stance strings using msg_contents.
  • Update defauklt website to show Telnet/SSL/SSH connect info. Added new SERVER_HOSTNAME setting for use in the server:port stanza.
  • Changed all at_before/after_* hooks to at_pre/post_* for consistency across Evennia (the old names still work but are deprecated)
  • Change settings.COMMAND_DEFAULT_ARG_REGEX default from None to a regex meaning that a space or / must separate the cmdname and args. This better fits common expectations.
  • Add confirmation question to ban/unban commands.
  • Check new teleport and teleport_here lock-types in teleport command to optionally allow to limit teleportation of an object or to a specific destination.
  • Add settings.MXP_ENABLED=True and settings.MXP_OUTGOING_ONLY=True as sane defaults, to avoid known security issues with players entering MXP links.
  • Add browser name to webclient CLIENT_NAME in session.protocol_flags, e.g. "Evennia webclient (websocket:firefox)" or "evennia webclient (ajax:chrome)".
  • TagHandler.add/has(tag=...) kwarg changed to add/has(key=...) for consistency with other handlers.
  • Make DefaultScript.delete, DefaultChannel.delete and DefaultAccount.delete return bool True/False if deletion was successful (like DefaultObject.delete before them)
  • contrib.custom_gametime days/weeks/months now always starts from 1 (to match the standard calendar form ... there is no month 0 every year after all).
  • AttributeProperty/NAttributeProperty to allow managing Attributes/NAttributes on typeclasses in the same way as Django fields.
  • Give build/system commands a @name to fall back to if the non-@ name is used by another command (like open and @open. If no duplicate, @ is optional.
  • Move legacy channel-management commands (ccreate, addcom etc) to a contrib since their work is now fully handled by the single channel command.
  • Expand examine command's code to much more extensible and modular. Show attribute categories and value types (when not strings).
  • AttributeHandler.remove(key, return_exception=False, category=None, ...) changed to .remove(key, category=None, return_exception=False, ...) for consistency.
  • New command cooldown contrib for making it easier to manage commands using dynamic cooldowns between uses (owllex)
  • Restructured contrib/ folder, placing all contribs as separate packages under subfolders. All imports will need to be updated.
  • Made MonitorHandler.add/remove support category for monitoring Attributes with a category (before only key was used, ignoring category entirely).
  • Move create_* functions into db managers, leaving utils.create only being wrapper functions (consistent with utils.search). No change of api otherwise.
  • Add support for $dbref() and $search when assigning an Attribute value with the set command. This allows assigning real objects from in-game.
  • Add ability to examine /script and /channel entities with examine command.
  • Homogenize manager search methods to return querysets and not lists.
  • Restructure unit tests to always honor default settings; make new parents in on location for easy use in game dir.
  • The Lunr search engine used by help excludes common words; the settings-list LUNR_STOP_WORD_FILTER_EXCEPTIONS can be extended to make sure common names are included.
  • Add .deserialize() method to _Saver* structures to help completely decouple structures from database without needing separate import.
  • Add run_in_main_thread as a helper for those wanting to code server code from a web view.
  • Update evennia.utils.logger to use Twisted's new logging API. No change in Evennia API except more standard aliases logger.error/info/exception/debug etc can now be used.
  • Have type/force default to update-mode rather than resetmode and add more verbose warning when using reset mode.
  • Attribute storage support defaultdics (Hendher)
  • Add ObjectParent mixin to default game folder template as an easy, ready-made way to override features on all ObjectDB-inheriting objects easily. source location, mimicking behavior of at_pre_move hook - returning False will abort move.
  • Add TagProperty, AliasProperty and PermissionProperty to assign these data in a similar way to django fields.
  • New at_pre_object_receive(obj, source_location) method on Objects. Called on destination, mimicking behavior of at_pre_move hook - returning False will abort move.
  • New at_pre_object_leave(obj, destination) method on Objects. Called on
  • The db pickle-serializer now checks for methods __serialize_dbobjs__ and __deserialize_dbobjs__ to allow custom packing/unpacking of nested dbobjs, to allow storing in Attribute.
  • Optimizations to rpsystem contrib performance. Breaking change: .get_sdesc() will now return None instead of .db.desc if no sdesc is set; fallback in hook (inspectorCaracal)
  • Reworked text2html parser to avoid problems with stateful color tags (inspectorCaracal)
  • Simplified EvMenu.options_formatter hook to use EvColumn and f-strings (inspectorcaracal)
  • Allow # CODE, # HEADER etc as well as #CODE/#HEADER in batchcode files - this works better with black linting.
  • Added move_type str kwarg to move_to() calls, optionally identifying the type of move being done ('teleport', 'disembark', 'give' etc). (volund)
  • Made RPSystem contrib msg calls pass pose or say as msg-type for use in e.g. webclient pane filtering where desired. (volund)
  • Added Account.uses_screenreader(session=None) as a quick shortcut for finding if a user uses a screenreader (and adjust display accordingly).

  • New at_server_init() hook called before all other startup hooks for all startup modes. Used for more generic overriding (volund)
  • New search lock type used to completely hide an object from being found by the DefaultObject.search (caller.search) method. (CloudKeeper)
  • Change setting MULTISESSION_MODE to now only control sessions, not how many characters can be puppeted simultaneously. New settings now control that.
  • Add new setting AUTO_CREATE_CHARACTER_WITH_ACCOUNT, a boolean deciding if the new account should also get a matching character (legacy MUD style).
  • Add new setting AUTO_PUPPET_ON_LOGIN, boolean deciding if one should automatically puppet the last/available character on connection (legacy MUD style)
  • Add new setting MAX_NR_SIMULTANEUS_PUPPETS - how many puppets the account can run at the same time. Used to limit multi-playing.
  • Make setting MAX_NR_CHARACTERS interact better with the new settings above.
  • Allow $search funcparser func to search tags and to accept kwargs for more powerful searches passed into the regular search functions.
  • spawner.spawn and linked methods now has a kwarg protfunc_raise_errors (default True) to disable strict errors on malformed/not-found protfuncs
  • Improve search performance when having many DB-based prototypes via caching.
  • Remove the return_parents kwarg of evennia.prototypes.spawner.spawn since it was inefficient and unused.
  • Made all id fields BigAutoField for all databases. (owllex)
  • EvForm refactored. New literals mapping, for literal mappings into the main template (e.g. for single-character replacements).
  • EvForm cells kwarg now accepts EvCells with custom formatting options (mainly for custom align/valign). EvCells now makes use of utils.justify.
  • utils.justify now supports align="a" (absolute alignments. This keeps the given left indent but crops/fills to the width. Used in EvCells.
  • EvTable now supports passing EvColumns as a list directly, (EvTable(table=[colA,colB]))
  • Add tags= search criterion to DefaultObject.search.
  • Add AT_EXIT_TRAVERSE signal, firing when an exit is traversed.

  • evennia.prototypes.search_prototype has a new kwarg require_single=False that raises a KeyError exception if query gave 0 or >1 results.
  • evennia.prototypes.spawner can now spawn by passing a prototype_key

Typeclasses

  • Add new methods on all typeclasses, useful specifically for object handling from the website/admin:
    • web_get_admin_url(): Returns the path to the object detail page in the Admin backend.
    • web_get_create_url(): Returns the path to the typeclass' creation page on the website, if implemented.
    • web_get_absolute_url(): Returns the path to the object's detail page on the website, if implemented.
    • web_get_update_url(): Returns the path to the object's update page on the website, if implemented.
    • web_get_delete_url(): Returns the path to the object's delete page on the website, if implemented.
  • All typeclasses have new helper class method create, which encompasses useful functionality that used to be embedded for example in the respective @create or @connect commands.
  • DefaultAccount now has new class methods implementing many things that used to be in unloggedin commands (these can now be customized on the class instead):
    • is_banned(): Checks if a given username or IP is banned.
    • get_username_validators: Return list of validators for username validation (see settings.AUTH_USERNAME_VALIDATORS)
    • authenticate: Method to check given username/password.
    • normalize_username: Normalizes names so (for Unicode environments) users cannot mimic existing usernames by replacing select characters with visually-similar Unicode chars.
    • validate_username: Mechanism for validating a username based on predefined Django validators.
    • validate_password: Mechanism for validating a password based on predefined Django validators.
    • set_password: Apply password to account, using validation checks.
  • AttributeHandler.remove and TagHandler.remove can now be used to delete by-category. If neither key nor category is given, they now work the same as .clear().

Protocols

  • Support for Grapevine MUD-chat network ("channels" supported)

Server

  • Convert ServerConf model to store its values as a Picklefield (same as Attributes) instead of using a custom solution.
  • OOB: Add support for MSDP LIST, REPORT, UNREPORT commands (re-mapped to msdp_list, msdp_report, msdp_unreport, inlinefuncs)
  • Added evennia.ANSIString to flat API.
  • Server/Portal log files now cycle to names on the form server_.log_19_03_08_ instead of server.log___19.3.8, retaining unix file sorting order.
  • Django signals fire for important events: Puppet/Unpuppet, Object create/rename, Login, Logout, Login fail Disconnect, Account create/rename

Settings

  • GLOBAL_SCRIPTS - dict defining typeclasses of global scripts to store on the new evennia.GLOBAL_SCRIPTS container. These will auto-start when Evennia start and will always exist.
  • OPTIONS_ACCOUNTS_DEFAULT - option dict with option defaults and Option classes
  • OPTION_CLASS_MODULES - classes representing an on-Account Option, on special form
  • VALIDATOR_FUNC_MODULES - (general) text validator functions, for verifying an input is on a specific form.

Utils

  • evennia launcher now fully handles all django-admin commands, like running tests in parallel.
  • evennia.utils.create.account now also takes tags and attrs keywords.
  • evennia.utils.interactive decorator can now allow you to use yield(secs) to pause operation in any function, not just in Command.func. Likewise, response = yield(question) will work if the decorated function has an argument or kwarg caller.
  • Added many more unit tests.
  • Swap argument order of evennia.set_trace to set_trace(term_size=(140, 40), debugger='auto') since the size is more likely to be changed on the command line.
  • utils.to_str(text, session=None) now acts as the old utils.to_unicode (which was removed). This converts to the str() type (not to a byte-string as in Evennia 0.8), trying different encodings. This function will also force-convert any object passed to it into a string (so force_string flag was removed and assumed always set).
  • utils.to_bytes(text, session=None) replaces the old utils.to_str() functionality and converts str to bytes.
  • evennia.MONITOR_HANDLER.all now takes keyword argument obj to only retrieve monitors from that specific Object (rather than all monitors in the entire handler).
  • Support adding \f in command doc strings to force where EvMore puts page breaks.
  • Validation Functions now added with standard API to homogenize user input validation.
  • Option Classes added to make storing user-options easier and smoother.
  • evennia.VALIDATOR_CONTAINER and evennia.OPTION_CONTAINER added to load these.

Contribs

  • Evscaperoom - a full puzzle engine for making multiplayer escape rooms in Evennia. Used to make the entry for the MUD-Coder's Guild's 2019 Game Jam with the theme "One Room", where it ranked #1.
  • Evennia game-index client no longer a contrib - moved into server core and configured with new setting GAME_INDEX_ENABLED.
  • The extended_room contrib saw some backwards-incompatible refactoring:
    • All commands now begin with CmdExtendedRoom. So before it was CmdExtendedLook, now it's CmdExtendedRoomLook etc.
    • The detail command was broken out of the desc command and is now a new, stand-alone command CmdExtendedRoomDetail. This was done to make things easier to extend and to mimic how the detail command works in the tutorial-world.
    • The detail command now also supports deleting details (like the tutorial-world version).
    • The new ExtendedRoomCmdSet includes all the extended-room commands and is now the recommended way to install the extended-room contrib.
  • Reworked menu_login contrib to use latest EvMenu standards. Now also supports guest logins.
  • Mail contrib was refactored to have optional Command classes CmdMail for OOC+IC mail (added to the CharacterCmdSet and CmdMailCharacter for IC-only mailing between chars (added to CharacterCmdSet)

Evennia 0.8

2017-2018 Released Nov 2018

Requirements

  • Up requirements to Django 1.11.x, Twisted 18 and pillow 5.2.0
  • Add inflect dependency for automatic pluralization of object names.

Server/Portal

  • Removed evennia_runner, completely refactor evennia_launcher.py (the 'evennia' program) with different functionality).
  • Both Portal/Server are now stand-alone processes (easy to run as daemon)
  • Made Portal the AMP Server for starting/restarting the Server (the AMP client)
  • Dynamic logging now happens using evennia -l rather than by interactive mode.
  • Made AMP secure against erroneous HTTP requests on the wrong port (return error messages).
  • The evennia istart option will start/switch the Server in foreground (interactive) mode, where it logs to terminal and can be stopped with Ctrl-C. Using evennia reload, or reloading in-game, will return Server to normal daemon operation.
  • For validating passwords, use safe Django password-validation backend instead of custom Evennia one.
  • Alias evennia restart to mean the same as evennia reload.

Prototype changes

  • New OLC started from olc command for loading/saving/manipulating prototypes in a menu.
  • Moved evennia/utils/spawner.py into the new evennia/prototypes/ along with all new functionality around prototypes.
  • A new form of prototype - database-stored prototypes, editable from in-game, was added. The old, module-created prototypes remain as read-only prototypes.
  • All prototypes must have a key prototype_key identifying the prototype in listings. This is checked to be server-unique. Prototypes created in a module will use the global variable name they are assigned to if no prototype_key is given.
  • Prototype field prototype was renamed to prototype_parent to avoid mixing terms.
  • All prototypes must either have typeclass or prototype_parent defined. If using prototype_parent, typeclass must be defined somewhere in the inheritance chain. This is a change from Evennia 0.7 which allowed 'mixin' prototypes without typeclass/prototype_key. To make a mixin now, give it a default typeclass, like evennia.objects.objects.DefaultObject and just override in the child as needed.
  • Spawning an object using a prototype will automatically assign a new tag to it, named the same as the prototype_key and with the category from_prototype.
  • The spawn command was extended to accept a full prototype on one line.
  • The spawn command got the /save switch to save the defined prototype and its key
  • The command spawn/menu will now start an OLC (OnLine Creation) menu to load/save/edit/spawn prototypes.

EvMenu

  • Added EvMenu.helptext_formatter(helptext) to allow custom formatting of per-node help.
  • Added evennia.utils.evmenu.list_node decorator for turning an EvMenu node into a multi-page listing.
  • A goto option callable returning None (rather than the name of the next node) will now rerun the current node instead of failing.
  • Better error handling of in-node syntax errors.
  • Improve dedent of default text/helptext formatter. Right-strip whitespace.
  • Add debug option when creating menu - this turns off persistence and makes the menudebug command available for examining the current menu state.

Webclient

  • Webclient now uses a plugin system to inject new components from the html file.
  • Split-windows - divide input field into any number of horizontal/vertical panes and assign different types of server messages to them.
  • Lots of cleanup and bug fixes.
  • Hot buttons plugin (friarzen) (disabled by default).

Locks

  • New function evennia.locks.lockhandler.check_lockstring. This allows for checking an object against an arbitrary lockstring without needing the lock to be stored on an object first.
  • New function evennia.locks.lockhandler.validate_lockstring allows for stand-alone validation of a lockstring.
  • New function evennia.locks.lockhandler.get_all_lockfuncs gives a dict {"name": lockfunc} for all available lock funcs. This is useful for dynamic listings.

Utils

  • Added new columnize function for easily splitting text into multiple columns. At this point it is not working too well with ansi-colored text however.
  • Extend the dedent function with a new baseline_index kwarg. This allows to force all lines to the indentation given by the given line regardless of if other lines were already a 0 indentation. This removes a problem with the original textwrap.dedent which will only dedent to the least indented part of a text.
  • Added exit_cmd to EvMore pager, to allow for calling a command (e.g. 'look') when leaving the pager.
  • get_all_typeclasses will return dict {"path": typeclass, ...} for all typeclasses available in the system. This is used by the new @typeclass/list subcommand (useful for builders etc).
  • evennia.utils.dbserialize.deserialize(obj) is a new helper function to completely disconnect a mutable recovered from an Attribute from the database. This will convert all nested _Saver* classes to their plain-Python counterparts.

General

  • Start structuring the CHANGELOG to list features in more detail.
  • Docker image evennia/evennia:develop is now auto-built, tracking the develop branch.
  • Inflection and grouping of multiple objects in default room (an box, three boxes)
  • evennia.set_trace() is now a shortcut for launching pdb/pudb on a line in the Evennia event loop.
  • Removed the enforcing of MAX_NR_CHARACTERS=1 for MULTISESSION_MODE 0 and 1 by default.
  • Add evennia.utils.logger.log_sec for logging security-related messages (marked SS in log).

Contribs

  • Auditing (Johnny): Log and filter server input/output for security purposes
  • Build Menu (vincent-lg): New @edit command to edit object properties in a menu.
  • Field Fill (Tim Ashley Jenkins): Wraps EvMenu for creating submittable forms.
  • Health Bar (Tim Ashley Jenkins): Easily create colorful bars/meters.
  • Tree select (Fluttersprite): Wrap EvMenu to create a common type of menu from a string.
  • Turnbattle suite (Tim Ashley Jenkins)- the old turnbattle.py was moved into its own turnbattle/ package and reworked with many different flavors of combat systems:
  • tb_basic - The basic turnbattle system, with initiative/turn order attack/defense/damage.
  • tb_equip - Adds weapon and armor, wielding, accuracy modifiers.
  • tb_items - Extends tb_equip with item use with conditions/status effects.
  • tb_magic - Extends tb_equip with spellcasting.
  • tb_range - Adds system for abstract positioning and movement.
  • The extended_room contrib saw some backwards-incompatible refactoring:
    • All commands now begin with CmdExtendedRoom. So before it was CmdExtendedLook, now it's CmdExtendedRoomLook etc.
    • The detail command was broken out of the desc command and is now a new, stand-alone command CmdExtendedRoomDetail. This was done to make things easier to extend and to mimic how the detail command works in the tutorial-world.
    • The detail command now also supports deleting details (like the tutorial-world version).
    • The new ExtendedRoomCmdSet includes all the extended-room commands and is now the recommended way to install the extended-room contrib.
  • Updates and some cleanup of existing contribs.

Overview-Changelogs

These are changelogs from a time before we used formal version numbers.

Sept 2017:

Release of Evennia 0.7; upgrade to Django 1.11, change 'Player' to 'Account', rework the website template and a slew of other updates. Info on what changed and how to migrate is found here: https://groups.google.com/forum/#!msg/evennia/0JYYNGY-NfE/cDFaIwmPBAAJ

Feb 2017:

New devel branch created, to lead up to Evennia 0.7.

Dec 2016:

Lots of bugfixes and considerable uptick in contributors. Unittest coverage and PEP8 adoption and refactoring.

May 2016:

Evennia 0.6 with completely reworked Out-of-band system, making the message path completely flexible and built around input/outputfuncs. A completely new webclient, split into the evennia.js library and a gui library, making it easier to customize.

Feb 2016:

Added the new EvMenu and EvMore utilities, updated EvEdit and cleaned up a lot of the batchcommand functionality. Started work on new Devel branch.

Sept 2015:

Evennia 0.5. Merged devel branch, full library format implemented.

Feb 2015:

Development currently in devel/ branch. Moved typeclasses to use django's proxy functionality. Changed the Evennia folder layout to a library format with a stand-alone launcher, in preparation for making an 'evennia' pypy package and using versioning. The version we will merge with will likely be 0.5. There is also work with an expanded testing structure and the use of threading for saves. We also now use Travis for automatic build checking.

Sept 2014:

Updated to Django 1.7+ which means South dependency was dropped and minimum Python version upped to 2.7. MULTISESSION_MODE=3 was added and the web customization system was overhauled using the latest functionality of django. Otherwise, mostly bug-fixes and implementation of various smaller feature requests as we got used to github. Many new users have appeared.

Jan 2014:

Moved Evennia project from Google Code to github.com/evennia/evennia.

Nov 2013:

Moved the internal webserver into the Server and added support for out-of-band protocols (MSDP initially). This large development push also meant fixes and cleanups of the way attributes were handled. Tags were added, along with proper handlers for permissions, nicks and aliases.

May 2013:

Made players able to control more than one Character at the same time, through the MULTISESSION_MODE=2 addition. This lead to a lot of internal changes for the server.

Oct 2012:

Changed Evennia from the Modified Artistic 1.0 license to the more standard and permissive BSD license. Lots of updates and bug fixes as more people start to use it in new ways. Lots of new caching and speed-ups.

March 2012:

Evennia's API has changed and simplified slightly in that the base-modules where removed from game/gamesrc. Instead admins are encouraged to explicitly create new modules under game/gamesrc/ when they want to implement their game - gamesrc/ is empty by default except for the example folders that contain template files to use for this purpose. We also added the ev.py file, implementing a new, flat API. Work is ongoing to add support for mud-specific telnet extensions, notably the MSDP and GMCP out-of-band extensions. On the community side, evennia's dev blog was started and linked on planet Mud-dev aggregator.

Nov 2011:

After creating several different proof-of-concept game systems (in contrib and privately) as well testing lots of things to make sure the implementation is basically sound, we are declaring Evennia out of Alpha. This can mean as much or as little as you want, admittedly - development is still heavy but the issue list is at an all-time low and the server is slowly stabilizing as people try different things with it. So Beta it is!

Aug 2011:

Split Evennia into two processes: Portal and Server. After a lot of work trying to get in-memory code-reloading to work, it's clear this is not Python's forte - it's impossible to catch all exceptions, especially in asynchronous code like this. Trying to do so results in hackish, flakey and unstable code. With the Portal-Server split, the Server can simply be rebooted while players connected to the Portal remain connected. The two communicates over twisted's AMP protocol.

May 2011:

The new version of Evennia, originally hitting trunk in Aug2010, is maturing. All commands from the pre-Aug version, including IRC/IMC2 support works again. An ajax web-client was added earlier in the year, including moving Evennia to be its own webserver (no more need for Apache or django-testserver). Contrib-folder added.

Aug 2010:

Evennia-griatch-branch is ready for merging with trunk. This marks a rather big change in the inner workings of the server, such as the introduction of TypeClasses and Scripts (as compared to the old ScriptParents and Events) but should hopefully bring everything together into one consistent package as code development continues.

May 2010:

Evennia is currently being heavily revised and cleaned from the years of gradual piecemeal development. It is thus in a very 'Alpha' stage at the moment. This means that old code snippets will not be backwards compatabile. Changes touch almost all parts of Evennia's innards, from the way Objects are handled to Events, Commands and Permissions.

April 2010:

Griatch takes over Maintainership of the Evennia project from the original creator Greg Taylor.

Older

Earlier revisions, with previous maintainer, used SVN on Google Code and have no changelogs.

First commit (Evennia's birthday) was November 20, 2006.
